There's an art to feeding pigs with homemade feed: keep these three precautions in mind
Whether for family or intensive pig farming, using homemade pig feed can greatly reduce feeding costs. However, when feeding homemade pig feed, you must grasp three "precautions." Pay attention to the types and proportions of raw materials. The commonly used raw material proportions for pig feed are: grains such as corn, rice, barley, and sorghum, which should generally account for 50%-70%; bran types such as wheat bran and rice bran, which should generally account for 10%-20%; toxic cottonseed cake, meal, and rapeseed cake, etc., should be less than 10%. Animal protein feeds such as fish meal

Can Keeping Chickens, Ducks, and Geese Together with Pigs Lead to Highly Pathogenic Avian Influenza?
Poultry should not be kept together with pigs, because influenza viruses from poultry can infect pigs, and human influenza viruses can also infect pigs. Since influenza viruses have 8 different nucleic acid segments, when these two different virus particles infect a single cell together, their nucleic acid segments undergo reassortment and rearrangement to produce new types of influenza virus particles. These new influenza virus particles can often cause major epidemics in humans, resulting in great harm. In addition, chickens should not be kept together with waterfowl such as ducks and geese, because

Key Technical Points and Care Methods for Keeping Phalaenopsis (Moth Orchid) Through the Summer
1. Measures: Getting Phalaenopsis through the summer is mainly a matter of cooling, and the following measures should be taken: ① Add a double layer of shade netting to reduce light, which achieves a good cooling effect (a drop of 2°C to 4°C). ② Sprinkle or flood the ground with water. Summer temperatures are very high, but the water just drawn from a well is actually very cold, around 16°C. Therefore, sprinkling or flooding with water can produce an obvious cooling effect. ③ Misting the leaves cools fastest, but the effect lasts the shortest time. ④ Ventilation. On the wall every 5

Research on Storage and Fresh-keeping Techniques for Jujube Fruit
Jujube is one of the fruit trees unique to China, with a cultivation history of over 2,000 years. The jujube tree is cold-resistant, drought-resistant and tolerant of poor soil, with strong adaptability, and is known as the "ironclad crop." Jujube fruit is rich in nutrients, containing more than twice the sugar of ordinary fruits as well as relatively large amounts of protein, fat, iron, phosphorus, calcium and other substances, and has high nutritional value and dietary therapy functions. Domestic research on fresh jujube storage and its postharvest physiology began in 1980, and studies and explorations have been carried out on the postharvest physiology and storage of jujube, with a great deal of work done on physiological and biochemical mechanisms.

Detailed Guide to Making Edible Mushroom Fresh-keeping Bags
1. Materials: hypophosphorous acid (50% aqueous solution), aluminum silicate (with an alumina content of 28%), gauze bags. 2. Making: ① Prepare the fresh-keeping agent: mix 1 part hypophosphorous acid and 1.2 parts aluminum silicate evenly, dry with hot air (a hot air blower may be used), then grind and pulverize, and finally pass through a 200-mesh sieve to obtain the fresh-keeping agent. ② Bagging: put the required amount of fresh-keeping agent into gauze bags (dosage 0.2-2 grams/bag) and seal them to obtain edible mushroom fresh-keeping bags. ③ Storage: fresh-keeping bags or fresh-keeping agent not used temporarily should be sealed and stored away from light.

How to keep edible mushrooms fresh? Ten practical methods shared
1. Cold storage preservation: After harvesting, the fresh mushrooms are sorted and placed in baskets, covered with multiple layers of wet gauze or burlap. In a cool place, place a vat containing a small amount of clean water, set a wooden rack above the water, place the baskets on the rack, and seal the vat opening with plastic film. 2. Dormancy preservation: After harvesting, place them indoors at above 25°C for 3-5 hours to encourage vigorous respiration, then place them in cold storage at around 0°C for about 12 hours; at around 20°C, the fresh-keeping period is about 4-5 days. 3. Controlled atmosphere preservation: This method artificially controls the temperature of the environment

What are the medication precautions for dogs? Owners should keep these points in mind
There are 4 commonly used methods of administration: oral, injection, enema and topical, and each of them has several ways. (1) Oral administration 1) Mixing with feed. Mix the drug directly into an appropriate amount of feed the dog likes and stir well, letting it eat on its own. If necessary, withhold one meal beforehand. This method is suitable when the sick dog still has an appetite and the drug has no unusual taste, is non-irritating and the dose is not large. 2) Oral dosing. When the dose of tablets, pills or capsules is not large, they can be wrapped directly in soft paper, the sick dog's mouth opened, and the packet placed over the tongue

What are the methods for keeping piglets warm when they are born in winter?
When sows give birth in winter, the cold weather affects piglet survival, especially for rural free-range households, which have neither farrowing crates nor warming facilities, so the survival rate of piglets born in winter is relatively low. For experienced sow breeders, building a small warm nest for newborn piglets is a good method to improve piglet survival and increase breeding returns. Below is an introduction to how to build a small warm nest for piglets: Before the sow gives birth, on one side of the pig pen, preferably in a sheltered, sunny spot, build a small nest 1 m long, 1 m wide and 50 cm high, and connect it to the pig pen with an opening for the pigs to pass through.
